Parasite Days: Survival Sim

"Good morning, Hostbody!"

In a not-so-distant future, the world is dying.

You wake up to find a strange but cute creature growing from your arm.

It is a parasite — one that drains its host's vitality.

Do you purge it... or will it purge you first?

The world's first parasite-raising survival adventure.
